Today when I ran yum update two packages came up microcode_ctl and unbound-libs. The updating process went fine until it outputted
Running transaction Updating : 2:microcode_ctl-2.1-61.6.el7_8.x86_64
then it just froze. I could no longer ssh to the machine and the console was just blank. I had to shut down it hard. It came back up seemingly fine. But yum update doesn't work anymore. It says "Error importing repomd.xml from base/7/x86_64: Damaged repomd.xml file" I looked at the logs, but journalctl only shows the latest boot on this machine.
So I guess I have three questions - Any idea what happened with the update process? - How can I repair repomd.xml? - How do I configure journalctl to store more boots?

I got the exact same problem few updates of microcode_ctl away but the consequences where terribly different (system broken at fs level, low level package files zero'ed, had to reconstruct from manually downloaded packages). How lucky your are, your yum transaction was including very few changes otherwise it could have broken much more. Since then, I excluded it this package from my yum updates. I reported this issue to the list:

- How can I repair repomd.xml?
- How do I configure journalctl to store more boots?
Sorry can't help there :-(.

Maybe related to https://www.hivelocity.net/blog/centos-update-advisory/ (discarding the blame game) it might be a bad combination of kernel/microcode/bios...
my 2 cents,

Thanks for the link. Very interesting as I also have a Supermicro motherboard. My journalctl outputs: kernel: DMI: Supermicro Super Server/X11SSM-F, BIOS 2.2 05/23/2018

No suggestions about the best way to restore repomd.xml?

Try:
yum --enablerepo=* clean all

Now that yum is up and running again it tells me the following
"There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction -- cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help)."
Doing "yum-complete-transaction --cleanup-only" should be safe, right? To clean up the botched microcode_ctl update and after that set it among excluded packages.

Is there some more information about this issue?
I've found this ticket https://bugs.centos.org/view.php?id=17452
I'm wondering how safe it is to update the microcode_ctl package on other Centos machines I have? They don't have a Supermicro motherboard.
Cheers Robin

I would say yes, but obviously there could be issues.
Intel provided the firmware .. Red Hat provided the source code. Our build seems correct.
If this is an issue, it is not a CentOS specific issue.
So, some BIOSes need upgraded to work with the latest firmware, etc.
I would check you Motherboard providers .. read about what firmware you need to run with which BIOS versions, etc.
